MKVI GTI with over 500 wheel horsepower? Yep, HSTuning takes the 2.0 Turbo in the MKVI GTI to 501 whp

It's nice to see MKVI GTI's making some serious power. There are few however crossing the 500 wheel horsepower threshold. To put this power in context, the car dyno'd below with just a tune was at the 230 wheel mark. That means HSTuning took this motor from 230 to 501 wheel horsepower for a gain of 271 horsepower at the wheels. That is some serious power game coming with some serious turbo boost on the relatively small 2.0 liter four-cylinder.

It would be nice to get more details and specs on what it took to reach this level as the fueling is no doubt a challenge. Unfortunately there have not been any updates from the tuner or owner for some months and all we really know is that it uses a "big turbo" which does not tell us much. Oh well, the motor is out getting built so this should be putting down even more power soon. Hopefully with some good documentation and a list of the specs to go with it. Dyno is below:

Yep, Skully, aka David@HStuning owns this. Race gas @ 35 PSI. I don't know if this is regular APR stage 3+ race gas file. Other similar setups with racegas only put down about 400whp on a dynojet as seen with the other threads. Still wish I knew more about this, but that's all I can shed for now.

Dave is running a billet wheel gt3071, on race fuel, and using a manual boost controller set at 35lbs of boost, that's why. Standard APR tune has boost at 24-25 max, which is why there is a huge power increase.

I'm running same turbo, similar set-up and making 470ish whp, at 26-27 lbs of boost..I'm working on fueling upgrades as we speak, and still on stock head. 500whp should be easily attainable after I'm done, still at same boost levels. No need to raise boost.

And FSI motors have hit well over 500whp.. USP has built a mk5 gti making over 600whp, and there are various guys on the golf mkv forum making 570-580+ whp..

Thank you for that last bit of information. I didn't think the standard aprstage3+ 100 octane file will max at 35 PSI lol.

You're at 470whp on 100 octane right? standard stage 3+ file?

Yes FSI motors have hit well over 500whp. Not on a 3071 though. They're all using 3076 or bigger with custom tuning on ATP turbo kits lol.

Well thanks for this, good post and info.

Sounds like the FSI isn't a bad way to go if one wants to mod for bigger power as the fueling seems to be figured out.

no problem. FSI is nice because there are more options available for it, but not for long. Just an FYI for you guys, I've got fueling figured out for the TSI my turbo is currently maxxed out, so I can't make any more power..but I did figure out fueling, so that's no longer an issue.

whoa whoa whoa, do you have WHP for the max out on the turbo? what are you going to upgrade to next?

That's awesome you figured out fueling, a lot of people are going to be very happy about that.

right now i am maxed out at 473whp on my gt3071r. Every set-up will vary a little bit.

Next things are my head, which I've been waiting on forever now. After the head, a custom intake manifold, and then custom t3 exhaust manifold with a bigger turbo. And some other bits and ends that I'm still thinking about..
